Abstract:
This article uses the different mortality rates of European colonialists to estimate the effect of institutions on economic performance. Europeans adopted very different colonization policies in different colonies. In places where mortality rates were high they did not settle, but set up extractive institutions that exist to the present day. By exploring the different mortality rates faced by soldiers, bishops and sailors in the colonies in the 17th, 18th and 19th Centuries, we were able to estimate the long-term effect of colonial institutions on per capita income.

Abstract:
We exploit differences in the mortality rates faced by European colonialists to estimate the effect of institutions on economic performance. Our argument is that Europeans adopted very different colonization policies in different colonies, with different associated institutions. The choice of colonization strategy was, at least in part, determined by whether Europeans could settle in the colony. In places where Europeans faced high mortality rates, they could not settle and they were more likely to set up worse (extractive) institutions. These early institutions persisted to the present. We document evidence supporting these hypotheses. Exploiting differences in mortality rates faced by soldiers, bishops and sailors in the colonies in the 17th, 18th, and 19th centuries as an instrument for current institutions, we estimate large effects of institutions on income per capita. Our estimates imply that differences in institutions explain approximately three-quarters of the income per capita differences across former colonies. Once we control for the effect of institutions, we find that countries in Africa or those closer to the equator do not have lower incomes.

Abstract:
Botswana has had the highest rate of per capita growth of any country in the world in the last 35 years. This occurred despite adverse initial conditions, including minimal investment during the colonial period and high inequality. Botswana achieved this rapid development by following orthodox economic policies. How Botswana sustained these policies is a puzzle because typically in Africa, 'good economics' has proved not to be politically feasible. In this Paper we suggest that good policies were chosen in Botswana because good institutions, which we refer to as institutions of private property, were in place. Why did institutions of private property arise in Botswana, but not other African nations? We conjecture that the following factors were important. First, Botswana possessed relatively inclusive pre-colonial institutions, placing constraints on political elites. Second, the effect of British colonialism on Botswana was minimal, and did not destroy these institutions. Third, following independence, maintaining and strengthening institutions of private property were in the economic interests of the elite. Fourth, Botswana is very rich in diamonds, which created enough rents that no group wanted to challenge the status quo at the expense of 'rocking the boat'. Finally, we emphasize that this situation was reinforced by a number of critical decisions made by the post-independence leaders, particularly Presidents Khama and Masire.

Abstract:
This Paper documents that the rise of (Western) Europe between 1500 and 1850 is largely accounted for by the growth of European nations with access to the Atlantic, and especially by those nations that engaged in colonialism and long distance oceanic trade. Moreover, Atlantic ports grew much faster than other West European cities, including Mediterranean ports. Atlantic trade and colonialism affected Europe both directly and indirectly by inducing institutional changes. In particular, the growth of New World, African and Asian trade after 1500 strengthened new segments of the commercial bourgeoisie and enabled these groups to demand, obtain and sustain changes in institutions to protect their property rights. Furthermore, the most significant institutional changes, and consequently the most substantial economic gains, occurred in nations where existing institutions placed some checks on the monarchy and particularly limited its control of overseas trading activities, thus enabling new merchants in these countries to benefit from Atlantic trade. Therefore, the Rise of Europe was largely the result of capitalist development driven by the interaction of late medieval institutions and the economic opportunities offered by 'Atlantic trade.'

Abstract:
This paper evaluates the importance of "property rights institutions," which protect citizens against expropriation by the government and powerful elites, and "contracting institutions," which enable private contracts between citizens. We exploit exogenous variation in both types of institutions driven by colonial history and document strong first-stage relationships between property rights institutions and the determinants of European colonization strategy (settler mortality and population density before colonization) and between contracting institutions and the identity of the colonizing power. Using this instrumental variables approach, we find that property rights institutions have a first-order effect on long-run economic growth, investment, and financial development. Contracting institutions appear to matter only for the form of financial intermediation. A possible explanation for this pattern is that individuals often find ways of altering the terms of their formal and informal contracts to avoid the adverse effects of weak contracting institutions but find it harder to mitigate the risk of expropriation in this way.

Abstract:
We develop a theory of political transitions inspired in part by the experiences of Western Europe and Latin America. Nondemocratic societies are controlled by a rich elite. The initially disenfranchised poor can contest power by threatening social unrest or revolution and this may force the elite to democratize. Democracy may not consolidate because it is more redistributive than a nondemocratic regime, and this gives the elite an incentive to mount a coup. Because inequality makes democracy more costly for the elite, highly unequal societies are less likely to consolidate democracy and may end up oscillating between regimes or in a nondemocratic repressive regime. An unequal society is likely to experience fiscal volatility, but the relationship between inequality and redistribution is nonmonotonic; societies with intermediate levels of inequality consolidate democracy and redistribute more than both very equal and very unequal countries. We also show that asset redistribution, such as educational and land reform, may be used to consolidate both democratic and nondemocratic regimes.

Abstract:
Among countries colonized by European powers during the past 500 years those that were relatively rich in 1500 are now relatively poor. We document this reversal using data on urbanization patterns and population density, which, we argue, proxy for economic prosperity. This reversal is inconsistent with a view that links economic development to geographic factors. According to the geography view, societies that were relatively rich in 1500 should also be relatively rich today. In contrast, the reversal is consistent with the role of institutions in economic development. The expansion of European overseas empires starting in the 15th century led to a major change in the institutions of the societies they colonized. In fact, the European intervention appears to have created an "institutional reversal" among these societies, in the sense that Europeans were more likely to introduce institutions encouraging investment in regions that were previously poor. This institutional reversal accounts for the reversal in relative incomes. We provide further support for this view by documenting that the reversal in relative incomes took place during the 19th century, and resulted from societies with good institutions taking advantage of industrialization opportunities.

Abstract:
We revisit one of the central empirical findings of the political economy literature that higher income per capita causes democracy. Existing studies establish a strong cross-country correlation between income and democracy, but do not typically control for factors that simultaneously affect both variables. We show that controlling for such factors by including country fixed effects removes the statistical association between income per capita and various measures of democracy. We also present instrumental-variables estimates using two different strategies. These estimates also show no causal effect of income on democracy. Furthermore, we reconcile the positive cross-country correlation between income and democracy with the absence of a causal effect of income on democracy by showing that the long-run evolution of income and democracy is related to historical factors. Consistent with this, the positive correlation between income and democracy disappears, even without fixed effects, when we control for the historical determinants of economic and political development in a sample of former European colonies.

Abstract:
Do societies choose inefficient policies and institutions, in contrast to what would be suggested by a reasoning extending the Coase Theorem to politics? Do societies choose inefficient policies and institutions because of differences in the beliefs and ideologies of their peoples or leaders? Or are inefficiencies in politics and economics the outcome of social and distributional conflicts? This paper discusses these various approaches to political economy, and develops the argument that there are strong empirical and theoretical grounds for believing that inefficient policies and institutions are prevalent, and that they are chosen because they serve the interests of politicians or social groups holding political power, at the expense of the society at large. At the center of the theoretical case are the commitment problems inherent in politics: parties holding political power cannot make commitments to bind their future actions because there is no outside agency with the coercive capacity to enforce such arrangements.

Abstract:
We show that even in the absence of diminishing returns in production and technological spillovers, international trade leads to a stable world income distribution. This is because specialization and trade introduce de facto diminishing returns - countries that accumulate capital faster than average experience declining export prices, depressing the rate of return to capital and discouraging further accumulation. Because of diminishing returns to capital accumulation at the country level, the cross-sectional behaviour of the world economy is similar to that of existing exogenous growth models. Cross-country variation in economic policies, savings and technology translate into cross-country variation in incomes, and country dynamics exhibit conditional convergence as in the Solow-Ramsey model. The dispersion of the world income distribution is determined by the forces that shape the strength of the terms of trade effects - the degree of openness to international trade and the extent of specialization. Finally, we provide evidence that countries accumulating faster experience a worsening in their terms of trade. Our estimates imply that, all else equal, a 1% faster growth is associated with approximately a 0.7% decline in the terms of trade.

Abstract:
We show that even in the absence of diminishing returns in production and techno-logical spillovers, international trade leads to a stable world income distribution. This is because specialization and trade introduce de facto diminishing returns: countries that accumulate capital faster than average experience declining export prices, depressing the rate of return to capital and discouraging further accumulation. Because of constant re-turns to capital accumulation from a global perspective time-series behavior of the world economy is similar to that of existing endogenous growth models, with the world growth rate determined by policies, savings and technologies. Because of diminishing returns to capital accumulation at the country level, the cross-sectional behavior of the world economy is similar to that of existing exogenous growth models: cross-country variation in economic policies, savings and technology translate into cross-country variation in incomes, and country dynamics exhibit conditional convergence as in the Solow-Ramsey model. The dispersion of the world income distribution is determined by the forces that shape the strength of the terms of trade effects the degree of openness to international trade and the extent of specialization. Finally, we provide evidence that countries accumulating faster experience a worsening in their terms of trade. Our estimates imply that, all else equal, a 1 percentage point faster growth is associated with approximately a 0.7 percentage point decline in the terms of trade.

Abstract:
We show that even in the absence of diminishing returns in production and technological spillovers, international trade leads to a stable world income distribution. This is because specialization and trade introduce de facto diminishing returns: Countries that accumulate capital faster than average experience declining export prices, depressing the rate of return to capital and discouraging further accumulation. Because of constant returns to capital accumulation at the country level, the cross-sectional behavior of the world economy is similar to that of existing exogenous growth models: Cross-country variation in economic policies, savings, and technology translate into cross-country variation in incomes, and country dynamics exhibit conditional convergence as in the Solow-Ramsey model. The dispersion of the world income distribution is determined by the forces that shape the strength of the terms of trade-effects--the degree of openness to international trade and the extent of specialization. Finally, we provide evidence that those countries accumulating faster experience a worsening in their terms of trade. Our estimates imply that, all else equal, a 1 percentage point faster growth is associated with approximately a 0.7 percentage point deline in the terms of trade.

Abstract:
We study the formation of a ruling coalition in political environments. Each individual is endowed with a level of political power. The ruling coalition consists of a subset of the individuals in the society and decides the distribution of resources. A ruling coalition needs to contain enough powerful members to win against any alternative coalition that may challenge it, and it needs to be self-enforcing, in the sense that none of its sub-coalitions should be able to secede and become the new ruling coalition. We first present an axiomatic approach that captures these notions and determines a (generically) unique ruling coalition. We then construct a simple dynamic game that encompasses these ideas and prove that the sequentially weakly dominant equilibria (and the Markovian trembling hand perfect equilibria) of this game coincide with the set of ruling coalitions of the axiomatic approach. We also show the equivalence of these notions to the core of a related non-transferable utility cooperative game. In all cases, the nature of the ruling coalition is determined by the power constraint, which requires that the ruling coalition be powerful enough, and by the enforcement constraint, which imposes that no sub-coalition of the ruling coalition that commands a majority is self-enforcing. The key insight that emerges from this characterization is that the coalition is made self-enforcing precisely by the failure of its winning sub-coalitions to be self-enforcing. This is most simply illustrated by the following simple finding: with a simple majority rule, while three-person (or larger) coalitions can be self-enforcing, two-person coalitions are generically not self-enforcing. Therefore, the reasoning in this paper suggests that three-person juntas or councils should be more common than two-person ones. In addition, we provide conditions under which the grand coalition will be the ruling coalition and conditions under which the most powerful individuals will not be included in the ruling coalition. We also use this framework to discuss endogenous party formation.

Abstract:
We study the formation of a ruling coalition in nondemocratic societies where institutions do not enable political commitments. Each individual is endowed with a level of political power. The ruling coalition consists of a subset of the individuals in the society and decides the distribution of resources. A ruling coalition needs to contain enough powerful members to win against any alternative coalition that may challenge it and it needs to be self-enforcing, in the sense that none of its subcoalitions should be able to secede and become the new ruling coalition. We present both an axiomatic approach that captures these notions and determines a (generically) unique ruling coalition and the analysis of a dynamic game of coalition formation that encompasses these ideas. We establish that the subgame perfect equilibria of the coalition formation game coincide with the set of ruling coalitions resulting from the axiomatic approach. A key insight of our analysis is that a coalition is made self-enforcing by the failure of its winning subcoalitions to be self-enforcing. This is most simply illustrated by the following example: with majority rule, two-person coalitions are generically not self-enforcing and consequently, three-person coalitions are self-enforcing (unless one player is disproportionately powerful). We also characterize the structure of ruling coalitions. For example, we determine the conditions under which ruling coalitions are robust to small changes in the distribution of power and when they are fragile. We also show that when the distribution of power across individuals is relatively equal and there is majoritarian voting, only certain sizes of coalitions (e.g., with majority rule, coalitions of size 3, 7, 15, 31, etc.) can be the ruling coalition.

Abstract:
This paper investigates the effect of (potential) market size on entry of new drugs and pharmaceutical innovation. Focusing on exogenous changes driven by U.S. demographic trends, we find that a 1 percent increase in the potential market size for a drug category leads to a 4 to 6 percent increase in the number of new drugs in that category. This response comes from both the entry of generic drugs and new non-generic drugs, and is generally robust to controlling for a variety of non-profit factors, pre-existing trends, and changes in health care coverage.

Abstract:
We analyze an economy where managers engage both in the adoption of technologies from the world frontier and in innovation activities. The selection of high-skill managers is more important for innovation activities. As the economy approaches the technology frontier, selection becomes more important. As a result, countries at early stages of development pursue an investment-based strategy, with long-term relationships, high average size and age of firms, large average investments, but little selection. Closer to the world technology frontier, there is a switch to an innovation-based strategy with short-term relationships, younger firms, less investment and better selection of managers. We show that relatively backward economies may switch out of the investment-based strategy too soon, so certain economic institutions and policies, such as limits on product market competition or investment subsidies, that encourage the investment-based strategy may be beneficial. However, societies that cannot switch out of the investment based strategy fail to converge to the world technology frontier. Non-convergence traps are more likely when policies and institutions are endogenized, enabling beneficiaries of existing policies to bribe politicians to maintain these policies.

Abstract:
We analyze an economy where managers engage both in the adaptation of technologies from the world frontier and in innovation activities. The selection of high-skill managers is more important for innovation activities. As the economy approaches the technology frontier, selection becomes more important. As a result, countires at early stages of development pursue an investment-based strategy, with long term relationships, high average size and age of firms, large average investments, but little selection. Closer to the world technology frontier, there is a switch to innovation-based strategy with short-term relationships, younger firms, less investment and better selection of managers. We show that relatively backward economies may switch out of the investment-based strategy too soon, so certain economic institutions and policies, such as limits on product market competition or investment subsidies, that encourage the investment-based strategy may be beneficial.

Abstract:
We construct a simple model where political elites may block technological and institutional development, because of a 'political replacement effect.' Innovations often erode elites' incumbency advantage, increasing the likelihood that they will be replaced. Fearing replacement, political elites are unwilling to initiate change, and may even block economic development. We show that elites are unlikely to block development when there is a high degree of political competition, or when they are highly entrenched. It is only when political competition is limited and also their power is threatened that elites will block development. We also show that such blocking is more likely to arise when political stakes are higher, and that external threats may reduce the incentives to block. We argue that this model provides an interpretation for why Britain, Germany and the US industrialized during the nineteenth century, while the landed aristocracy in Russia and Austria-Hungary blocked development.

Abstract:
Becker's theory of human capital predicts that minimum wages should reduce training investments for affected workers because they prevent these workers from taking wage cuts necessary to finance training. In contrast, in noncompetitive labor markets, minimum wages tend to increase training of affected workers because they induce firms to train their unskilled employees. We provide new estimates on the impact of the state and federal increases in the minimum wage between 1987 and 1992 on the training of low wage workers. We find no evidence that minimum wages reduce training, and little evidence that they tend to increase training. We therefore develop a hybrid model where minimum wages reduce the training investments of workers who were taking wage cuts to finance their training, while increasing the training of other workers. Finally, we provide some evidence consistent with this hybrid model.

Abstract:
This paper develops a model where this is a trade-off between the enforcement of the property rights of different groups. An 'oligarchic' society, where political power is in the hands of major producers, protects their property rights, but also tends to erect significant entry barriers, violating the property rights of future producers. Democracy, where political power is more widely diffused, imposes redistributive taxes on the producers, but tends to avoid entry barriers. When taxes in democracy are high and the distortions caused by entry barriers are low, an oligarchic society achieves greater efficiency. Nevertheless, because comparative advantage in entrepreneurship shifts away from the incumbents, the inefficiency created by entry barriers in oligarchy deteriorates over time. The typical pattern is therefore one of the rise and decline of oligarchic societies: of two otherwise identical societies, the one with an oligarchic organization will first become richer, but later fall behind the democratic society. I also discuss how democratic societies may be better able to take advantage of new technologies, and how the unequal distribution of income in an oligarchic society supports the oligarchic institutions and may keep them in place even when they become significantly costly to society.

Abstract:
This paper revisits the induced innovation literature of the 1960s to which Phelps was a major contributor (Drandakis and Phelps, 1965). This literature was the first systematic study of the determinants of technical change and also the first investigation of the relationship between factor prices and technical change. I present a modern reformulation of this literature based on the tools developed by the endogenous growth literature. This reformulation confirms many of the insights of the induced innovations literature, but reveals a new force, which I refer to as the market size effect: there will be more technical change directed at more abundant factors. I use this modern reformulation to shed light on two recent debates: (1) why is technical change often skill biased, and why has it become more skill biased during recent decades? (2) What is the role of human capital differences in accounting for income differences across countries? Interestingly, an application of this modern reformulation to these debates also reiterates some of the insights of another important paper by Phelps, Nelson and Phelps (1966).

Abstract:
We construct a model of simultaneous change and persistence in institutions. The model consists of landowning elites and workers, and the key economic decision concerns the form of economic institutions regulating the transaction of labor (e.g., competitive markets versus labor repression). The main idea is that equilibrium economic institutions are a result of the exercise of de jure and de facto political power. A change in political institutions, for example a move from nondemocracy to democracy, alters the distribution of de jure political power, but the elite can intensify their investments in de facto political power, such as lobbying or the use of paramilitary forces, to partially or fully offset their loss of de jure power. In the baseline model, equilibrium changes in political institutions have no effect on the (stochastic) equilibrium distribution of economic institutions, leading to a particular form of persistence in equilibrium institutions, which we refer to as invariance. When the model is enriched to allow for limits on the exercise of de facto power by the elite in democracy or for costs of changing economic institutions, the equilibrium takes the form of a Markov regime-switching process with state dependence. Finally, when we allow for the possibility that changing political institutions is more difficult than altering economic institutions, the model leads to a pattern of captured democracy, whereby a democratic regime may survive, but choose economic institutions favoring the elite. The main ideas featuring in the model are illustrated using historical examples from the U.S. South, Latin America and Liberia.

Abstract:
We present a tractable framework for the analysis of the relationship between contract incompleteness, technological complementarities and the division of labor. In the model economy, a firm decides the division of labor and contracts with its worker-suppliers on a subset of activities they have to perform. Worker-suppliers choose their investment levels in the remaining activities anticipating the ex post bargaining equilibrium. We show that greater contract incompleteness reduces both the division of labor and the equilibrium level of productivity given the division of labor. The impact of contract incompleteness is greater when the tasks performed by different workers are more complementary. We also discuss the effects of imperfect credit markets on the division of labor and productivity, and study the choice between the employment relationship versus an organizational form relying on outside contracting. Finally, we derive the implications of our framework for productivity differences and comparative advantage across countries.

Abstract:
The conventional wisdom views high levels of education as a prerequisite for democracy. This paper shows that existing evidence for this view is based on cross-sectional correlations, which disappear once we look at within-country variation. In other words, there is no evidence that countries that increase their education are more likely to become democratic.

Abstract:
The economics profession has made considerable progress in understanding the increase in wage inequality in the U.S. and the UK over the past several decades, but currently lacks a consensus on why inequality did not increase, or increased much less, in (continental) Europe over the same time period. I review the two most popular explanations for these differential trends: that relative supply of skills increased faster in Europe, and that European labor market institutions prevented inequality from increasing. I argue that these two explanations go some way towards accounting for the differential cross-country inequality trends, but do not provide an entirely satisfactory explanation. In addition, it appears that relative demand for skills increased differentially across countries. Motivated by this reasoning, I develop a simple theory where labor market institutions creating wage compression in Europe also encourage more investment in technologies increasing the productivity of less-skilled workers, thus implying less skill-biased technical change in Europe than in the U.S.

Abstract:
The French Revolution of 1789 had a momentous impact on neighboring countries. The French Revolutionary armies during the 1790s and later under Napoleon invaded and controlled large parts of Europe. Together with invasion came various radical institutional changes. French invasion removed the legal and economic barriers that had protected the nobility, clergy, guilds, and urban oligarchies and established the principle of equality before the law. The evidence suggests that areas that were occupied by the French and that underwent radical institutional reform experienced more rapid urbanization and economic growth, especially after 1850. There is no evidence of a negative effect of French invasion. Our interpretation is that the Revolution destroyed (the institutional underpinnings of) the power of oligarchies and elites opposed to economic change; combined with the arrival of new economic and industrial opportunities in the second half of the 19th century, this helped pave the way for future economic growth. The evidence does not provide any support for several other views, most notably, that evolved institutions are inherently superior to those 'designed'; that institutions must be 'appropriate' and cannot be 'transplanted'; and that the civil code and other French institutions have adverse economic effects.

Abstract:
This paper revisits and critically re-evaluates the widely-accepted modernization hypothesis which claims that per capita income causes the creation and the consolidation of democracy. We argue that existing studies find support for this hypothesis because they fail to control for the presence of omitted variables. There are many underlying historical factors that affect both the level of income per capita and the likelihood of democracy in a country, and failing to control for these factors may introduce a spurious relationship between income and democracy. We show that controlling for these historical factors by including fixed country effects removes the correlation between income and democracy, as well as the correlation between income and the likelihood of transitions to and from democratic regimes. We argue that this evidence is consistent with another well-established approach in political science, which emphasizes how events during critical historical junctures can lead to divergent political-economic development paths, some leading to prosperity and democracy, others to relative poverty and non-democracy. We present evidence in favor of this interpretation by documenting that the fixed effects we estimate in the post-war sample are strongly associated with historical variables that have previously been used to explain diverging development paths within the former colonial world.

Abstract:
Why do inefficient %uF818 non-growth enhancing %uF818 institutions emerge and persist? This paper develops a simple framework to provide some answers to this question. Political institutions determine the allocation of political power, and economic institutions determine the framework for policy-making and place constraints on various policies. Groups with political power, the elite, choose policies to increase their income and to directly or indirectly transfer resources from the rest of society to themselves. The baseline model encompasses various distinct sources of inefficient policies, including revenue extraction, factor price manipulation and political consolidation. Namely, the elite may pursue inefficient policies to extract revenue from other groups, to reduce their demand for factors, thus indirectly benefiting from changes in factor prices, and to impoverish other groups competing for political power. The elite%u2019s preference over inefficient policies translates into inefficient economic institutions. Institutions that can restrict inefficient policies will in general not emerge, and the elite may manipulate economic institutions in order to further increase their income or facilitate rent extraction. The exception is when there are commitment (holdup) problems, so that equilibrium taxes and regulations are worse than the elite would like them to be from an ex ante point of view. In this case, economic institutions that provide additional security of property rights to other groups can be useful. The paper concludes by providing a framework for the analysis of institutional change and institutional persistence.

Abstract:
During the nineteenth century, most Western societies extended the franchise, a decision which led to unprecedented redistributive programs. We argue that these political reforms can be viewed as strategic decisions by political elites to prevent widespread social unrest and revolution. Political transition, rather than redistribution under existing political institutions, occurs because current transfers do not ensure future transfers, while the extension of the franchise changes the future political equilibrium and acts as a commitment to future redistribution. Our theory offers a novel explanation for the Kuznets curve, whereby the fall in inequality follows redistribution due to democratization. We characterize the conditions under which an economy experiences the development path associated with the Kuznets curve, as opposed to two non-democratic paths; an `autocratic disaster', with high inequality and low output; and an `East Asian Miracle', with low inequality and high output.

Abstract:
External certification of workplace skills obtained through on-the-job training is widespread in many countries. This may indicate that training is financed by workers, and certification serves to assure the quality of the training offered by the firm. However, other evidence shows that general training is financed by firms, especially in Germany. We show in this paper that external certification of training may also be necessary for an equilibrium with firm-sponsored training. Firm financing of training is only possible if firms have monopsony power over the workers after training. If the training firm can extract too much of the employment rents, however, workers may not have sufficient incentives to put forth effort during training. Certification increases the values of training to the outside market, and hence to workers, making firm-sponsored training possible.

Abstract:
Average schooling in US states is highly correlated with state wage levels, even after controlling for the direct effect of schooling on individual wages. We use an instrumental variables strategy to determine whether this relationship is driven by social returns to education. The instrumentals for average schooling are derived from information on the child labor laws and compulsory attendance laws that affected men in our Census samples, while quarter of birth is used as an instrument for individual schooling. This results in precisely estimated private returns to education of about seven percent, and small social returns, typically less than one percent, that are not significantly different from zero.

Abstract:
An agent with a misperception may have an evolutionary advantage when others recognize his misperception and its behavioral implications. In such situations evolutionary forces can lead to misperceptions, yielding "irrational behavior," such as the play of strictly dominated strategies. We point out that this reasoning relies on the assumption of subjective rationality-agents are assumed to choose the behavior that maximizes their perceived payoffs. However, subjective rationality does not have solid evolutionary foundations: in the presence of misperceptions, agents who do not maximize their perceived payoffs may have greater fitness than those who do. We show that relaxing the subjective rationality requirement, somewhat paradoxically, leads to effectively rational behavior: although agents may have systematic misperceptions, they will develop other biases to undo these misperceptions, and will act as if they are rational. As a result, systematic biases in experimental settings may not necessarily translate into irrational behavior. We also demonstrate that the same evolutionary forces, in the long run, lead agents to play as if they have a common prior, even though each agent will have different and possibly incorrect perceptions of payoffs and the rules of the game.

Abstract:
This paper develops the thesis that credit market frictions may be an important contributor to high unemployment in Europe. When a change in the technological regime necessitates the creation of new firms, this can happen relatively rapidly in the U.S. where credit markets function efficiently. In contrast, in Europe, job creation is constrained by credit market imperfections, so unemployment rises and remains high for an extended period. The data show that there has not been slower growth in the most credit dependent industries in Europe relative to the U.S., but the share of employment in these industries is lower than in the U.S. This suggests that although credit market imperfections are unlikely to have been the major cause of the increase in European unemployment, they may have played some role in limiting European employment growth.

Abstract:
Most economic analyses presume that there are limited differences in the prior beliefs of individuals, as assumption most often justified by the argument that sufficient common experiences and observations will eliminate disagreements. We investigate this claim using a simple model of Bayesian learning. Two individuals with different priors observe the same infinite sequence of signals about some underlying parameter. Existing results in the literature establish that when individuals are certain about the interpretation of signals, under very mild conditions there will be asymptotic agreement - their assessments will eventually agree. In contrast, we look at an environment in which individuals are uncertain about the interpretation of signals, meaning that they have non-degenerate probability distributions over the conditional distribution of signals given the underlying parameter. When priors on the parameter and the conditional distribution of signals have full support, we prove the following results: (1) Individuals will never agree, even after observing the same infinite sequence of signals. (2) Before observing the signals, they believe with probability 1 that their posteriors about the underlying parameter will fail to converge. (3) Observing the same sequence of signals may lead to a divergence of opinion rather than the typically presumed convergence. We then characterize the conditions for asymptotic agreement under approximate certainty - i.e., as we look at the limit where uncertainty about the interpretation of the signals disappears. When the family of probability distributions of signals given the parameter has rapidly-varying tails (such as the normal or exponential distributions), approximate certainty restores asymptotic agreement. However, when the family of probability distributions has regularly-varying tails (such as the Pareto, the log-normal, and the t-distributions), asymptotic agreement does not obtain even in the limit as the amount of uncertainty disappears. Lack of common priors has important implications for economic behavior in a range of circumstances. We illustrate how the type of learning outlined in this paper interacts with economic behavior in various different situations, including games of common interest, coordination, asset trading and bargaining.

Abstract:
Most economic analyses presume that there are limited differences in the prior beliefs of individuals, an assumption most often justified by the argument that sufficient common experiences and observations will eliminate disagreements. We investigate this claim using a simple model of Bayesian learning. Two individuals with different priors observe the same infinite sequence of signals about some underlying parameter. Existing results in the literature establish that when individuals are certain about the interpretation of signals, under very mild conditions there will be asymptotic agreement - their assessments will eventually agree. In contrast, we look at an environment in which individuals are uncertain about the interpretation of signals, meaning that they have non-degenerate probability distributions over the conditional distribution of signals given the underlying parameter. When priors on the parameter and the conditional distribution of signals have full support, we prove the following results: (1) Individuals will never agree, even after observing the same infinite sequence of signals. (2) Before observing the signals, they believe with probability 1 that their posteriors about the underlying parameter will fail to converge. (3) Observing the same sequence of signals may lead to a divergence of opinion rather than the typically-presumed convergence. We then characterize the conditions for asymptotic agreement under "approximate certainty" - i.e., as we look at the limit where uncertainty about the interpretation of the signals disappears. When the family of probability distributions of signals given the parameter has "rapidly-varying tails" (such as the normal or the exponential distributions), approximate certainty restores asymptotic agreement. However, when the family of probability distributions has "regularly-varying tails" (such as the Pareto, the log-normal, and the t-distributions), asymptotic agreement does not obtain even in the limit as the amount of uncertainty disappears. Lack of common priors has important implications for economic behavior in a range of circumstances. We illustrate how the type of learning outlined in this paper interacts with economic behavior in various different situations, including games of common interest, coordination, asset trading and bargaining.

Abstract:
This paper develops a framework to analyze the relationship between the diffusion of new technologies and the decentralization decisions of firms. Centralized control relies on the information of the principal, which we equate with publicly available information. Decentralized control, on the other hand, delegates authority to a manager with superior information. However, the manager can use her informational advantage to make choices that are not in the best interest of the principal. As the available public information about the specific technology increases, the trade-off shifts in favor of centralization. We show that firms closer to the technological frontier, firms in more heterogeneous environments and younger firms are more likely to choose decentralization. Using three datasets of French and British firms in the 1990s, we report robust correlations consistent with these predictions.

Abstract:
I analyze an economy in which firms can undertake both labor- and capital-augmenting technological improvements. In the long run, the economy resembles the standard growth model with purely labor-augmenting technical change, and the share of labor in GDP is constant. Along the transition path, however, there is capital-augmenting technical change and factor shares change. Tax policy and changes in labor supply or savings typically change factor shares in the short run, but have no or little effect on the long-run factor distribution of income.

Abstract:
Many developing countries have suffered under the personal rule of kleptocrats', who implement highly inefficient economic policies, expropriate the wealth of their citizens, and use the proceeds for their own glorification or consumption. We argue that the success of kleptocrats rests, in part, on their ability to use a divide-and-rule' strategy, made possible by weaknesses in the institutions in these societies. Members of society need to cooperate in order to depose a kleptocrat, yet such cooperation may be defused by imposing punitive rates of taxation on any citizen who proposes such a move, and redistributing the benefits to those who need to agree to it. Thus the collective action problem can be intensified by threats which remain off the equilibrium path. In equilibrium, all are exploited and no one challenges the kleptocrat. Kleptocratic policies are more likely when foreign aid and rents from natural resources provide rulers with substantial resources to buy off opponents; when opposition groups are shortsighted; when the average productivity in the economy is low; and when there is greater inequality between producer groups (because more productive groups are more difficult to buy off).

Abstract:
Many developing countries have suffered under the personal rule of 'kleptocrats', who implement highly inefficient economic policies, expropriate the wealth of their citizens, and use the proceeds for their own glorification or consumption. The incidence of kleptocracy is a serious impediment to development. Yet how do kleptocrats survive? How can they apparently exploit the entire citizenship of countries and not foment successful opposition? In this research we argue that the success of kleptocrats rests on their ability to use a particular type of political strategy, which we refer to as 'divide-and-rule'. Members of society need to cooperate in order to depose a kleptocrat. A kleptocrat, however, may defuse such cooperation by imposing punitive rates of taxation on any citizen who proposes such a move, and redistributing the benefits to those who need to agree to it. Thus kleptocrats can intensify the collective action problem by threats that remain off the equilibrium path. In equilibrium, all are exploited and no one challenges the kleptocrat because of the threat of divide-and-rule. The divide-and-rule strategy is made possible by the weakness of the institutions in these societies, and highlights the different nature of politics between strongly- and weakly-institutionalized polities. We show that foreign aid and rents from natural resources typically help kleptocratic rulers by providing them with greater resources to buy off opponents. Kleptocratic policies are also more likely to arise when opposition groups are shortsighted and when the average productivity in the economy is low. We also find that greater inequality between producer groups may constrain kleptocratic policies because more productive groups are more difficult to buy off.

Abstract:
This paper investigates the effects of female labor supply on the wage structure. To identify variation in female labor supply, we exploit the military mobilization for World War II, which drew many women into the workforce as males exited civilian employment. The extent of mobilization was not uniform across states, however, with the fraction of eligible males serving ranging from 41 to 54 percent. We find that in states with greater mobilization of men, women worked substantially more after the War and in 1950, though not in 1940. We interpret these differentials as labor supply shifts induced by the War. We find that increases in female labor supply lower female wages, lower male wages, and increase the college and premium and male wage inequality generally. Our findings indicate that at mid-century, women were closer substitutes to high school graduate and relatively low-skill males, but not to those with the lowest skills.

Abstract:
This paper investigates the effects of increased female labor supply on the labor market. To identify a source of exogenous variation in female labor supply, we exploit differences in female labor force participation before and after WWII. The War drew many women into the labor force as men left for overseas. The extent of mobilization for the War was not uniform across states, however. While in some states almost 55 percent of eligible males exited the labor market for military service, in other states the mobilization rate was just over 40 percent. We find that in states with greater mobilization of men, women worked substantially more in the immediate aftermath of the War and in 1950, though not in 1940. We interpret the differential growth in female labor force participation between 1940 and 1950 as corresponding to shifts in women's labor supply induced by the War, and use state mobilization rates as an instrument to study the consequences of greater female labor supply for the labor market. We find that greater female labor supply: (1) Leads to lower female wages; a 10 percent increase in female employment reduces female earnings by 7 to 11 percent; (2) Leads to lower male wages; a 10 percent increase in female employment reduces male earnings by 4 to 6 percent; (3) Increases the college premium and wage inequality among males generally. Our findings suggest that in the aftermath of WWII, women were closer substitutes to high school graduate and relatively low-skill males, but not to those with less than high school and the lowest skills.

Abstract:
We exploit the changes in the distribution of family income to estimate the effect of parental resources on college education. Our strategy exploits the fact that families at the bottom of the income distribution were much poorer in the 1990s than they were in the 1970s, while the opposite is true for families in the top quartile of the distribution. Our estimates suggest large effects of family income on enrollments. For example, we find that a 10 percent increase in family income is associated with a 1.4 percent increase in the probability of attending a four-year college.

Abstract:
We investigate how nondemocratic regimes use the military and how this can lead to the emergence of military dictatorships. Nondemocratic regimes need the use of force in order to remain in power, but this creates a political moral hazard problem' a strong military may not simply work as an agent of the elite but may turn against them in order to create a regime more in line with their own objectives. The political moral hazard problem increases the cost of using repression in nondemocratic regimes and in particular, necessitates high wages and policy concessions to the military. When these concessions are not sufficient, the military can take action against a nondemocratic regime in order to create its own dictatorship. A more important consequence of the presence of a strong military is that once transition to democracy takes place, the military poses a coup threat against the nascent democratic regime until it is reformed. The anticipation that the military will be reformed in the future acts as an additional motivation for the military to undertake coups against democratic governments. We show that greater inequality makes the use of the military in nondemocratic regimes more likely and also makes it more difficult for democracies to prevent military coups. In addition, greater inequality also makes it more likely that nondemocratic regimes are unable to solve the political moral hazard problem and thus creates another channel for the emergence of military dictatorships. We also show that greater natural resource rents make military coups against democracies more likely, but have ambiguous effects on the political equilibrium in nondemocracies (because with abundant natural resources, repression becomes more valuable to the elite, but also more expensive to maintain because of the more severe political moral hazard problem that natural resources induce). Finally, we discuss how the national defense role of the military interacts with its involvement in domestic politics.

Abstract:
This paper investigates the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple incomplete contracts model. Then, we investigate these predictions using plant-level data for the UK manufacturing sector. Most importantly, and consistent with theory, we find that the technology intensities of downstream (producer) and upstream (supplier) industries have opposite effects on the likelihood of vertical integration. Also consistent with theory, both these effects are stronger when the supplying industry accounts for a large fraction of the producer's costs. These results are generally robust and hold with alternative measures of technology intensity, with alternative estimation strategies, and with or without controlling for a number of firm and industry-level characteristics.

Abstract:
This paper investigates the determinants of vertical integration using data from the UK manufacturing sector. We find that the relationship between a downstream (producer) industry and an upstream (supplier) industry is more likely to be vertically integrated when the producing industry is more technology intensive and the supplying industry is less technology intensive. Moreover, both of these effects are stronger when the supplying industry accounts for a large fraction of the producer's costs. These results are generally robust and hold with alternative measures of technology intensity, with alternative estimation strategies, and with or without controlling for a number of firm and industry-level characteristics. They are consistent with the incomplete contract theories of the firm that emphasize both the potential costs and benefits of vertical integration in terms of investment incentives.

Abstract:
We study the optimal Mirrlees taxation problem in a dynamic economy with idiosyncratic (productivity or preference) shocks. In contrast to the standard approach, which implicitly assumes that the mechanism is operated by a benevolent planner with full commitment power, we assume that any centralized mechanism can only be operated by a self-interested ruler/government without commitment power, who can therefore misuse the resources and the information it collects. An important result of our analysis is that there will be truthful revelation along the equilibrium path (for all positive discount factors), which shows that truth-telling mechanisms can be used despite the commitment problems and the different interests of the government. Using this tool, we show that if the government is as patient as the agents, the best sustainable mechanism leads to an asymptotic allocation where the aggregate distortions arising from political economy disappear. In contrast, when the government is less patient than the citizens, there are positive aggregate distortions and positive aggregate capital taxes even asymptotically. Under some additional assumptions on preferences, these results generalize to the case when the government is benevolent but unable to commit to future tax policies. We conclude by providing a brief comparison of centralized mechanisms operated by self-interested rulers to anonymous markets.

Abstract:
We study the efficiency of oligopoly equilibria in congested markets. The motivating examples are the allocation of network flows in a communication network or of traffic in a transportation network. We show that increasing competition among oligopolists can reduce efficiency, measured as the difference between users' willingness to pay and delay costs. We characterize a tight bound of 5/6 on efficiency in pure strategy equilibria. This bound is tight even when the number of routes and oligopolists is arbitrarily large. We also study the efficiency properties of mixed strategy equilibria.

We show that increasing competition among oligopolists can reduce efficiency, measured as the difference between users' willingness to pay and delay costs. We characterize a tight bound of 5/6 on efficiency in pure strategy equilibria when there is zero latency at zero flow and a tight bound of 2√2-2 with positive latency at zero flow. These bounds are tight even when the numbers of routes and oligopolists are arbitrarily large.

Abstract:
Regimes controlled by a rich elite often collapse and make way for democracy amidst widespread social unrest. Such regime changes are often followed by redistribution to the poor at the expense of the former elite. We argue that the reason why the elite may have to resort to full-scale democratization, despite its apparent costs to themselves, may be that lesser concessions would be viewed as a sign of weakness and spur further unrest and more radical demands. The elite may therefore be forced to choose between repression and the most generous concession, a transition to full democracy.

Abstract:
Inefficiencies in the bureaucratic organization of the state are often viewed as important factors in retarding economic development. Why certain societies choose or end up with such inefficient organizations has received very little attention, however. In this paper, we present a simple theory of the emergence and persistence of inefficient states. The society consists of rich and poor individuals. The rich are initially in power, but expect to transition to democracy, which will choose redistributive policies. Taxation requires the employment of bureaucrats. We show that, under certain circumstances, by choosing an inefficient state structure, the rich may be able to use patronage and capture democratic politics. This enables them to reduce the amount of redistribution and public good provision in democracy. Moreover, the inefficient state creates its own constituency and tends to persist over time. Intuitively, an inefficient state structure creates more rents for bureaucrats than would an efficient state structure. When the poor come to power in democracy, they will reform the structure of the state to make it more efficient so that higher taxes can be collected at lower cost and with lower rents for bureaucrats. Anticipating this, when the society starts out with an inefficient organization of the state, bureaucrats support the rich, who set lower taxes but also provide rents to bureaucrats. We show that in order to generate enough political support, the coalition of the rich and bureaucrats may not only choose an inefficient organization of the state, but they may further expand the size of bureaucracy so as to gain additional votes. The model shows that an equilibrium with an inefficient state is more likely to arise when there is greater inequality between the rich and the poor, when bureaucratic rents take intermediate values and when individuals are sufficiently forward-looking.

Abstract:
This paper constructs a model of non-balanced economic growth. The main economic force is the combination of differences in factor proportions and capital deepening. Capital deepening tends to increase the relative output of the sector with a greater capital share, but simultaneously induces a reallocation of capital and labor away from that sector. We first illustrate this force using a general two-sector model. We then investigate it further using a class of models with constant elasticity of substitution between two sectors and Cobb-Douglas production functions in each sector. In this class of models, non-balanced growth is shown to be consistent with an asymptotic equilibrium with constant interest rate and capital share in national income. We also show that for realistic parameter values, the model generates dynamics that are broadly consistent with US data. In particular, the model generates more rapid growth of employment in less capital-intensive sectors, more rapid growth of real output in more capital-intensive sectors and aggregate behavior in line with the Kaldor facts. Finally, we construct and analyze a model of "non-balanced endogenous growth," which extends the main results of the paper to an economy with endogenous anddirected technical change. This model shows that equilibrium will typically involve endogenous non-balanced technological progress.

Abstract:
This Paper develops the empirical and theoretical case that differences in economic institutions are the fundamental cause of differences in economic development. We first document the empirical importance of institutions by focusing on two 'quasi-natural experiments' in history, the division of Korea into two parts with very different economic institutions and the colonization of much of the world by European powers starting in the fifteenth century. We then develop the basic outline of a framework for thinking about why economic institutions differ across countries. Economic institutions determine the incentives of and the constraints on economic actors, and shape economic outcomes. As such, they are social decisions, chosen for their consequences. Because different groups and individuals typically benefit from different economic institutions, there is generally a conflict over these social choices, ultimately resolved in favor of groups with greater political power. The distribution of political power in society is in turn determined by political institutions and the distribution of resources. Political institutions allocate de jure political power, while groups with greater economic might typically possess greater de facto political power. We, therefore, view the appropriate theoretical framework as a dynamic one with political institutions and the distribution of resources as the state variables. These variables themselves change over time because prevailing economic institutions affect the distribution of resources, and because groups with de facto political power today strive to change political institutions in order to increase their de jure political power in the future. Economic institutions encouraging economic growth emerge when political institutions allocate power to groups with interests in broad-based property rights enforcement, when they create effective constraints on power-holders, and when there are relatively few rents to be captured by power-holders. We illustrate the assumptions, the workings and the implications of this framework using a number of historical examples.

Abstract:
What form of intellectual property rights (IPR) policy contributes to economic growth? Should technological followers be able to license the products of technological leaders? Should a company with a large technological lead receive the same IPR protection as a company with a more limited lead? We develop a general equilibrium framework to investigate these questions. The economy consists of many industries and firms engaged in cumulative (step-by-step) innovation. IPR policy regulates whether followers in an industry can copy the technology of the leader and also how much they have to pay to license past innovations. With full patent protection, followers can catch up to the leader in their industry either by making the same innovation(s) themselves or by making some pre-specified payments to the technological leaders. We prove the existence of a steady-state equilibrium and characterize some of its properties. We then quantitatively investigate the implications of different types of IPR policy on the equilibrium growth rate. The two major results of this exercise are as follows. First, the growth rate in the standard models used in the (growth) literature can be improved significantly by introducing a simple form of licensing. Second, we show that full patent protection is not optimal from the viewpoint of maximizing the growth rate of the economy and that the growth-maximizing policy involves state-dependent IPR protection, providing greater protection to technological leaders that are further ahead than those that are close to their followers. This form of the growth-maximizing policy is a result of the trickle-down effect, which implies that providing greater protection to firms that are further ahead of their followers than a certain threshold increases the R&D incentives also for all technological leaders that are less advanced than this threshold.

Abstract:
Is inequality harmful for economic growth? Is the underdevelopment of Latin America related to its unequal distribution of wealth? A recently emerging consensus claims not only that economic inequality has detrimental effects on economic growth in general, but also that differences in economic inequality across the American continent during the 19th century are responsible for the radically different economic performances of the north and south of the continent. In this paper we investigate this hypothesis using unique 19th century micro data on land ownership and political office holding in the state of Cundinamarca, Colombia. Our results shed considerable doubt on this consensus. Even though Cundinamarca is indeed more unequal than the Northern United States at the time, within Cundinamarca municipalities that were more unequal in the 19th century (as measured by the land gini) are more developed today. Instead, we argue that political rather than economic inequality might be more important in understanding long-run development paths and document that municipalities with greater political inequality, as measured by political concentration, are less developed today. We also show that during this critical period the politically powerful were able to amass greater wealth, which is consistent with one of the channels through which political inequality might affect economic allocations. Overall our findings shed doubt on the conventional wisdom and suggest that research on long-run comparative development should investigate the implications of political inequality as well as those of economic inequality.

Abstract:
The study of the bias of new technologies is important both as part of the analysis of the nature of technology adoption and the direction of technological change, and to understand the distributional implications of new technologies. In this paper, I analyze the equilibrium bias of technology. I distinguish between the relative bias of technology, which concerns how the marginal product of a factor changes relative to that of another following the introduction of new technology, and the absolute bias, which looks only at the effect of new technology on the marginal product of a factor. The first part of the paper generalizes a number of existing results in the literature regarding the relative bias of technology. In particular, I show that when the menu of technological possibilities only allows for factor-augmenting technologies, the increase in the supply of a factor always induces technological change (or technology adoption) relatively biased towards that factor. This force can be strong enough to make the relative marginal product of a factor increasing in response to an increase in its supply, thus leading to an upward-sloping relative demand curve. However, I also show that the results about relative bias do not generalize when more general menus of technological possibilities are considered. In the second part of the paper, I show that there are much more general results about absolute bias. I prove that under fairly mild assumptions, an increase in the supply of a factor always induces changes in technology that are absolutely biased towards that factor, and these results hold both for small changes and large changes in supplies. Most importantly, I also determine the conditions under which the induced-technology response will be strong enough so that the price (marginal product) of a factor increases in response to an increase in its supply. These conditions correspond to a form of failure of joint concavity of the aggregate production function of the economy in factors and technology. This type of failure of joint concavity is quite possible in economies where equilibrium factor demands and technologies are decided by different agents.

Abstract:
The study of the bias of new technologies is important both as part of the analysis of the nature of technology adoption and the direction of technological change, and to understand the distributional implications of new technologies. In this paper, I analyze the equilibrium bias of technology. I distinguish between the relative bias of technology, which concerns how the marginal product of a factor changes relative to that of another following the introduction of new technology, and the absolute bias, which looks only at the effect of new technology on the marginal product of a factor. The first part of the paper generalizes a number of existing results in the literature regarding the relative bias of technology. In particular, I show that when the menu of technological possibilities only allows for factor-augmenting technologies, the increase in the supply of a factor always induces technological change (or technology adoption) relatively biased towards that factor. This force can be strong enough to make the relative marginal product of a factor increasing in response to an increase in its supply, thus leading to an upward-sloping relative demand curve. However, I also show that the results about relative bias do not generalize when more general menus of technological possibilities are considered. In the second part of the paper, I show that there are much more general results about absolute bias. I prove that under fairly mild assumptions, an increase in the supply of a factor always induces changes in technology that are absolutely biased towards that factor, and these results hold both for small changes and large changes in supplies. Most importantly, I also determine the conditions under which the induced-technology response will be strong enough so that the price (marginal product) of a factor increases in response to an increase in its supply. These conditions correspond to a form of failure of joint concavity of the aggregate production function of the economy in factors and technology. This type of failure of joint concavity is quite possible in economies where equilibrium factor demands and technologies are decided by different agents.

Abstract:
We propose a model in which economic relations and institutions in advanced and less developed economies differ as these societies have access to different amounts of information. This lack of information makes it hard to give the right incentives to managers and entrepreneurs. We argue that differences in the amount of information arise because of the differences in the scale of activities in rich and poor economies; namely, there is too little repetition of similar activities in poor economies, thus insufficient information to set the appropriate standards for firm performance. Our model predicts a number of institutional and structural transformations as the economy accumulates capital and information.

Abstract:
We document a statistical association between the severity of the mass murder of Jews (the Holocaust) by the Nazis during World War II and long-run economic and political outcomes within Russia. Cities that experienced the Holocaust most intensely have grown less and administrative districts (oblasts) where the Holocaust had the largest impact have lower urban populations, GDP per capita and lower average wages today. In addition these same cities and oblasts exhibit a higher vote share for Communist candidates since the collapse of the Soviet Union. Although we cannot rule out the possibility that these statistical relationships are caused by other factors, the overall patterns appear generally robust. We provide evidence on one possible mechanism that we hypothesize may link the Holocaust to the present -- the change it induced in the social structure, in particular the size of the middle class, across different regions of Russia. Before World War II, Russian Jews were predominantly in white collar (middle class) occupations and the Holocaust appears to have had a direct negative effect on the size of the middle class after the war.

Abstract:
We study the efficiency of oligopoly equilibria in a model where firms compete over capacities and prices. The motivating example is a communication network where service providers invest in capacities and then compete in prices. Our model economy corresponds to a two-stage game. First, firms (service providers) independently choose their capacity levels. Second, after the capacity levels are observed, they set prices. Given the capacities and prices, users (consumers) allocate their demands across the firms. We first establish the existence of pure strategy subgame perfect equilibria (oligopoly equilibria) and characterize the set of equilibria. These equilibria feature pure strategies along the equilibrium path, but off-the-equilibrium path they are supported by mixed strategies. We then investigate the efficiency properties of these equilibria, where efficiency is defined as the ratio of surplus in equilibrium relative to the first best. We show that efficiency in the worst oligopoly equilibria of this game can be arbitrarily low. However, if the best oligopoly equilibrium is selected (among multiple equilibria), the worst-case efficiency loss has a tight bound, approximately equal to 5/6 with 2 firms. This bound monotonically decreases towards zero when the number of firms increases. We also suggest a simple way of implementing the best oligopoly equilibrium. With two firms, this involves the lower-cost firm acting as a Stackelberg leader and choosing its capacity first. We show that in this Stackelberg game form, there exists a unique equilibrium corresponding to the best oligopoly equilibrium. We also show that an alternative game form where capacities and prices are chosen simultaneously always fails to have a pure strategy equilibrium. These results suggest that the timing of capacity and price choices in oligopolistic environments is important both for the existence of equilibrium and for the extent of efficiency losses in equilibrium.

Abstract:
This paper argues that unemployment insurance increases labor productivity by encouraging workers to seek higher productivity jobs, and by encouraging firms to create those jobs. We use a quantitative general equilibrium model to investigate whether this effect is comparable in magnitude to the standard moral hazard effects of unemployment insurance. Our model economy captures the behavior of the U.S. labor market for high school graduates quite well. When unemployment insurance becomes more generous starting from the current U.S. levels, there is an increase in unemployment similar in magnitude to the micro-estimates, but because the composition of jobs also changes, total output and welfare increase as well.

Abstract:
A central feature of dynamic collective decision-making is that the rules that govern the procedures for future decision-making and the distribution of political power across players are determined by current decisions. For example, current constitutional change must take into account how the new constitution may pave the way for further changes in laws and regulations. We develop a general framework for the analysis of this class of dynamic problems. Under relatively natural acyclicity assumptions, we provide a complete characterization of dynamically stable states as functions of the initial state and determine conditions for their uniqueness. We show how this framework can be applied in political economy, coalition formation, and the analysis of the dynamics of clubs. The explicit characterization we provide highlights two intuitive features of dynamic collective decision-making: (1) a social arrangement is made stable by the instability of alternative arrangements that are preferred by sufficiently many members of the society; (2) efficiency-enhancing changes are often resisted because of further social changes that they will engender.

Abstract:
We provide a model to investigate the tension between information aggregation and spread of misinformation in large societies (conceptualized as networks of agents communicating with each other). Each individual holds a belief represented by a scalar. Individuals meet pairwise and exchange information, which is modeled as both individuals adopting the average of their pre-meeting beliefs. When all individuals engage in this type of information exchange, the society will be able to effectively aggregate the initial information held by all individuals. There is also the possibility of misinformation, however, because some of the individuals are "forceful," meaning that they influence the beliefs of (some) of the other individuals they meet, but do not change their own opinion. The paper characterizes how the presence of forceful agents interferes with information aggregation. Under the assumption that even forceful agents obtain some information (however infrequent) from some others (and additional weak regularity conditions), we first show that beliefs in this class of societies converge to a consensus among all individuals. This consensus value is a random variable, however, and we characterize its behavior. Our main results quantify the extent of misinformation in the society by either providing bounds or exact results (in some special cases) on how far the consensus value can be from the benchmark without forceful agents (where there is efficient information aggregation). The worst outcomes obtain when there are several forceful agents and forceful agents themselves update their beliefs only on the basis of information they obtain from individuals most likely to have received their own information previously.

Abstract:
We study the efficiency properties of oligopoly equilibria in congested networks. Our measure of efficiency is the difference between users' willingness to pay and delay costs. Previous work has demonstrated that in networks consisting of parallel links, efficiency losses from competition are bounded. In contrast, in this paper we show that in the presence of serial links, the efficiency loss relative to the social optimum can be arbitrarily large because of the double marginalization problem, whereby each serial provider charges high prices not taking into account the effect of this strategy on the profits of other providers along the same path. Nevertheless, when there are no delay costs without transmission (i.e., latencies at zero are equal to zero), irrespective of the number of serial and parallel providers, the efficiency of strong oligopoly equilibria can be bounded by 1/2, where strong oligopoly equilibria are equilibria in which each provider plays a strict best response and all of the traffic is transmitted. However, even with strong oligopoly equilibria, inefficiency can be arbitrarily large when the assumption of no delay costs without transmission is relaxed.

Abstract:
This paper studies a simple model of experimentation and innovation. Our analysis suggests that patents may improve the allocation of resources by encouraging rapid experimentation and efficient ex post transfer of knowledge across firms. Each firm receives a private signal on the success probability of one of many potential research projects and decides when and which project to implement. A successful innovation can be copied by other firms. Symmetric equilibria (where actions do not depend on the identity of the firm) always involve delayed and staggered experimentation, whereas the optimal allocation never involves delays and may involve simultaneous rather than staggered experimentation. The social cost of insufficient experimentation can be arbitrarily large. Appropriately-designed patents can implement the socially optimal allocation (in all equilibria). In contrast to patents, subsidies to experimentation, research, or innovation cannot typically achieve this objective. We also show that when signal quality differs across firms, the equilibrium may involve a nonmonotonicity, whereby players with stronger signals may experiment after those with weaker signals. We show that in this more general environment patents again encourage experimentation and reduce delays.

Abstract:
We revisit one of the central empirical findings of the political economy literature that higher income per capita causes democracy. Existing studies establish a strong cross-country correlation between income and democracy, but do not typically control for factors that simultaneously affect both variables. We show that controlling for such factors by including country fixed effects removes the statistical association between income per capita and various measures of democracy. We also present instrumental-variables estimates using two different strategies. These estimates also show no causal effect of income on democracy. Furthermore, we reconcile the positive cross-country correlation between income and democracy with the absence of a causal effect of income on democracy by showing that the long-run evolution of income and democracy is related to historical factors. Consistent with this, the positive correlation between income and democracy disappears, even without fixed effects, when we control for the historical determinants of economic and political development in a sample of former European colonies.

Abstract:
We study the structure of nonlinear incentive-compatible taxes, in a dynamic economy subject to political economy and commitment problems. In contrast to existing analyses of dynamic and/or nonlinear taxation problems, we relax the assumptions that taxes are set by a benevolent government and that there is commitment to policies. Instead, in our model economy taxes are set by a self-interested politician, without any commitment power. This politician is partly controlled by the citizens via elections. The resulting environment is one of a dynamic mechanism design without commitment. We focus on the best sustainable mechanism, which is the mechanism that maximizes the ex ante utility of the citizens. Towards a full characterization of the allocations implied by the best sustainable mechanism, we first prove that a version of the revelation principle applies in our environment and that attention can be restricted to direct truth-telling mechanisms. Using this result, we prove that the provision of incentives to politicians can be separated from the provision of incentives to, and from redistribution, across individuals. This also enables us to develop a method of characterizing the best sustainable mechanism as a solution to a standard dynamic mechanism design problem subject to additional political economy and commitment constraints formulated only as functions of aggregate variables. Using this formulation, we provide conditions under which distortions created by political economy and commitment problems persist or disappear in the long run. In particular, if politicians are as patient as (or more patient than) the citizens, these distortions disappear asymptotically, and they remain positive otherwise. Finally, we extend our analysis to the case where the government cares both about its own consumption and the future utility of the citizens. This extension generalizes our results to environments where the key constraint is the time-inconsistency of a (partially) benevolent government.

Abstract:
Under the assumption that individuals know the conditional distributions of signals given the payoff-relevant parameters, existing results conclude that as individuals observe infinitely many signals, their beliefs about the parameters will eventually merge. We first show that these results are fragile when individuals are uncertain about the signal distributions: given any such model, a vanishingly small individual uncertainty about the signal distributions can lead to a substantial (non-vanishing) amount of differences between the asymptotic beliefs. We then characterize the conditions under which a small amount of uncertainty leads only to a small amount of asymptotic disagreement. According to our characterization, this is the case if the uncertainty about the signal distributions is generated by a family with "rapidly-varying tails" (such as the normal or the exponential distributions). However, when this family has "regularly-varying tails" (such as the Pareto, the log-normal, and the t-distributions), a small amount of uncertainty leads to a substantial amount of asymptotic disagreement.

Abstract:
Countries that have pursued distortionary macroeconomic policies, including high inflation, large budget deficits and misaligned exchange rates, appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period. Does this reflect the causal effect of these macroeconomic policies on economic outcomes? One reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak 'institutions', including political institutions that do not constrain politicians and political elites, ineffective enforcement of property rights for investors, widespread corruption, and a high degree of political instability. This Paper documents that countries that inherited more 'extractive' institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period. More specifically, societies where European colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises. Based on our previous work, we interpret this relationship as due to the causal effect of institutions on economic outcomes: Europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality. Once we control for the effect of institutions, macroeconomic policies appear to have only a minor impact on volatility and crises. This suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic volatility, and also that the effects of institutional differences on volatility do not appear to be primarily mediated by any of the standard macroeconomic variables. Instead, it appears that weak institutions cause volatility through a number of microeconomic, as well as macroeconomic, channels.

Abstract:
We construct a model of simultaneous change and persistence in institutions. The model consists of landowning elites and workers, and the key economic decision concerns the form of economic institutions regulating the transaction of labour (e.g., competitive markets versus labour repression). The main idea is that equilibrium economic institutions are a result of the exercise of de jure and de facto political power. A change in political institutions, for example a move from non-democracy to democracy, alters the distribution of de jure political power, but the elite can intensify their investments in de facto political power, such as lobbying or the use of paramilitary forces, to partially or fully offset their loss of de jure power. In the baseline model, equilibrium changes in political institutions have no effect on the (stochastic) equilibrium distribution of economic institutions, leading to a particular form of persistence in equilibrium institutions, which we refer to as invariance. When the model is enriched to allow for limits on the exercise of de facto power by the elite in democracy or for costs of changing economic institutions, the equilibrium takes the form of a Markov regime-switching process with state dependence. Finally, when we allow for the possibility that changing political institutions is more difficult than altering economic institutions, the model leads to a pattern of captured democracy, whereby a democratic regime may survive, but choose economic institutions favouring the elite. The main ideas featuring in the model are illustrated using historical examples from the US South, Latin America and Liberia.

Abstract:
This paper studies the conditions under which the scarcity of a factor (in particular, labor) encourages technological progress and technology adoption. In standard endogenous growth models, which feature a strong scale effect, an increase in the supply of labor encourages technological progress. In contrast, the famous Habakkuk hypothesis in economic history claims that technological progress was more rapid in 19th-century United States than in Britain because of labor scarcity in the former country. Similar ideas are often suggested as possible reasons for why high wages might have encouraged rapid adoption of certain technologies in continental Europe over the past several decades, and as a potential reason for why environmental regulations can spur more rapid innovation. I present a general framework for the analysis of these questions. I define technology as strongly labor saving if the aggregate production function of the economy exhibits decreasing differences in the appropriate index of technology, and labor. Conversely, technology is strongly labor complementary if the production function exhibits increasing differences in and labor. The main result of the paper shows that labor scarcity will encourage technological advances if technology is strongly labor saving. In contrast, labor scarcity will discourage technological advances if technology is strongly labor complementary. I provide examples of environments in which technology can be strongly labor saving and also show that such a result is not possible in certain canonical macroeconomic models. These results clarify the conditions under which labor scarcity and high wages encourage technological advances and the reason why such results were obtained or conjectured in certain settings, but do not always apply in many models used in the growth literature.

Conversely, technology is strongly labor complementary if the production function exhibits increasing differences in theta and labor. The main result of the paper shows that labor scarcity will encourage technological advances if technology is strongly labor saving. In contrast, labor scarcity will discourage technological advances if technology is strongly labor complementary.

Abstract:
We document substantial within-country (cross-municipality) differences in incomes for a large number of countries in the Americas. A significant fraction of the within-country differences cannot be explained by observed human capital. We conjecture that the sources of within-country and between-country differences are related. As a first step towards a united framework, we propose a simple model incorporating both differences in technological know-how across countries and differences in productive efficiency within countries.

Abstract:
We study the determinants of vertical integration in a new dataset of over 750,000 firms from 93 countries. Existing evidence suggests the presence of large cross-country differences in the organization of firms, which may be related to differences in financial development, contracting costs or regulation. We find cross-country correlations between vertical integration on the one hand and financial development, contracting costs, and entry barriers on the other that are consistent with these "priors". Nevertheless, we also show that these correlations are almost entirely driven by industrial composition; countries with more limited financial development, higher contracting costs or greater entry barriers are concentrated in industries with a high propensity for vertical integration. Once we control for differences in industrial composition, none of these factors are correlated with average vertical integration. However, we also find a relatively robust differential effect of financial development across industries; countries with less-developed financial markets are significantly more integrated in industries that are more human capital or technology intensive.

Abstract:
The Americans With Disabilities Act (ADA) requires employers to accommodate disabled workers and outlaws discrimination against the disabled in hiring, firing, and pay. Although the ADA was meant to increase employment of the disabled, it also increases costs for employers. The net theoretical impact turns on which provisions of the ADA are most important and how responsive firm entry and exit is to profits. Empirical results using the CPS suggest that the ADA had a negative effect on the employment of disabled men of all working ages and disabled women under age 40. The effects appear to be larger in medium size firms, possibly because small firms were exempt from the ADA. The effects are also larger in states where there have been more ADA-related discrimination charges. Estimates of effects on hiring and firing suggest the ADA reduced hiring of the disabled but did not affect separations. This weighs against a pure firing-costs interpretation of the ADA. Finally, there is little evidence of an impact on the nondisabled, suggesting that the adverse employment consequences of the ADA have been limited to the protected group.

Abstract:
We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and discourages innovation. Outsourcing of some production activities mitigates the managerial overload, but creates a holdup problem, causing some of the rents of the owners to be dissipated to the supplier. Far from the technology frontier, imitation activities are more important, and vertical integration is preferred. Closer to the frontier, the value of innovation increases, encouraging outsourcing.

Abstract:
Most large-scale communication networks, such as the Internet, consist of interconnected administrative domains. While source (or selfish) routing, where transmission follows the least cost path for each source, is reasonable across domains, service providers typically engage in traffic engineering to improve operating performance within their own network. Motivated by this observation, we develop and analyze a model of partially optimal routing, where optimal routing within subnetworks is overlaid with selfish routing across domains. We demonstrate that optimal routing within a subnetwork does not necessarily improve the performance of the overall network. In particular, when Braess' paradox occurs in the network, partially optimal routing may lead to worse overall network performance. We provide bounds on the worst-case loss of efficiency that can occur due to partially optimal routing. For example, when all congestion costs can be represented by affine latency functions and all administrative domains have a single entry and exit point, the worst-case loss of efficiency is no worse than 25% relative to the optimal solution. In the presence of administrative domains incorporating multiple entry and/or exit points, however, the performance of partially optimal routing can be arbitrarily inefficient even with linear latencies. We also provide conditions for traffic engineering to be individually optimal for service providers.

Abstract:
A notable feature of post-World War II civil wars is their very long average duration. We provide a theory of the persistence of civil wars. The civilian government can successfully defeat rebellious factions only by creating a relatively strong army. In weakly-institutionalized polities this opens the way for excessive influence or coups by the military. Civilian governments whose rents are largely unaffected by civil wars then choose small and weak armies that are incapable of ending insurrections. Our framework also shows that when civilian governments need to take more decisive action against rebels, they may be forced to build over-sized armies, beyond the size necessary for fighting the insurrection, as a commitment to not reforming the military in the future.

Abstract:
We study dynamic selection of governments under different political institutions, with a special focus on institutional "flexibility". A government consists of a subset of the individuals in the society. The competence level of the government in office determines collective utilities (e.g., by determining the amount and quality of public goods), and each individual derives additional utility from being part of the government (e.g., corruption or rents from holding office). We characterize dynamic evolution of governments and determine the structure of stable governments, which arise and persist in equilibrium. Perfect democracy, where current members of the government do not have an incumbency advantage or special powers, always leads to the emergence of the most competent government. However, any deviation from perfect democracy destroys this result. There is always at least one other, less competent government that is also stable and can persist forever, and even the least competent government can persist forever in office. Moreover, a greater degree of democracy may lead to worse governments. In contrast, in the presence of stochastic shocks or changes in the environment, greater democracy corresponds to greater flexibility and increases the probability that high competence governments will come to power. This result suggests that a particular advantage of democratic regimes may be their greater adaptability to changes rather than their performance under given conditions. Finally, we show that, in the presence of stochastic shocks, "royalty-like" dictatorships may be more successful than "junta-like" dictatorships, because they might also be more adaptable to change.

Abstract:
In aggregative games, each player's payoff depends on her own actions and an aggregate of the actions of all the players (for example, sum, product or some moment of the distribution of actions). Many common games in industrial organization, political economy, public economics, and macroeconomics can be cast as aggregative games. In most of these situations, the behavior of the aggregate is of interest both directly and also indirectly because the comparative statics of the actions of each player can be obtained as a function of the aggregate. In this paper, we provide a general and tractable framework for comparative static results in aggregative games. We focus on two classes of aggregative games: (1) aggregative of games with strategic substitutes and (2) "nice" aggregative games, where payoff functions are continuous and concave in own strategies. We provide simple sufficient conditions under which "positive shocks" to individual players increase their own actions and have monotone effects on the aggregate. We show how this framework can be applied to a variety of examples and how this enables more general and stronger comparative static results than typically obtained in the literature.

Abstract:
We study the perfect Bayesian equilibrium of a model of learning over a general social network. Each individual receives a signal about the underlying state of the world, observes the past actions of a stochastically-generated neighborhood of individuals, and chooses one of two possible actions. The stochastic process generating the neighborhoods defines the network topology (social network). The special case where each individual observes all past actions has been widely studied in the literature. We characterize pure-strategy equilibria for arbitrary stochastic and deterministic social networks and characterize the conditions under which there will be asymptotic learning - that is, the conditions under which, as the social network becomes large, individuals converge (in probability) to taking the right action. We show that when private beliefs are unbounded (meaning that the implied likelihood ratios are unbounded), there will be asymptotic learning as long as there is some minimal amount of expansion in observations. Our main theorem shows that when the probability that each individual observes some other individual from the recent past converges to one as the social network becomes large, unbounded private beliefs are sufficient to ensure asymptotic learning. This theorem therefore establishes that, with unbounded private beliefs, there will be asymptotic learning an almost all reasonable social networks. We also show that for most network topologies, when private beliefs are bounded, there will not be asymptotic learning. In addition, in contrast to the special case where all past actions are observed, asymptotic learning is possible even with bounded beliefs in certain stochastic network topologies.

Abstract:
Although almost half of the world's population lives under nondemocratic regimes, the questions of how policy decisions are made and how power changes hands in nondemocracies have received relatively little attention in the political economy literature. Gordon Tullock (1987) suggested that because there are no strong institutions ensuring consensus and regulating the election and succession of leaders, non-democratic regimes rapidly degenerate into personal rule, where a single dictator dominates every aspect of decision-making. In this paper, we draw on our work on dynamic coalition formation and investigate Tullock's conjecture formally. Our game-theoretic analysis leads to the opposite of Tullock's conjecture: provided that players are sufficiently forward-looking, juntas do not dynamically converge to personal rule. On the contrary, relatively large juntas may emerge and persist as ruling coalitions for a very simple and intuitive reason: the absence of strong institutions not only enables some junta members to eliminate others, but also implies that current members cannot make credible commitments and in particular cannot refrain from engaging in further rounds of elimination.

Abstract:
In this essay I review the new book by Torsten Persson and Guido Tabellini, The Economic Effects of Constitutions, which investigates the policy and economic consequences of different forms of government and electoral rules. I also take advantage of this opportunity to discuss the advantages and disadvantages of a number of popular empirical strategies in the newly emerging field of comparative political economy.

Abstract:
What is the effect of increasing life expectancy on economic growth? To answer this question, we exploit the international epidemiological transition, the wave of international health innovations and improvements that began in the 1940s. We obtain estimates of mortality by disease before the 1940s from the League of Nations and national public health sources. Using these data, we construct an instrument for changes in life expectancy, referred to as predicted mortality, which is based on the pre-intervention distribution of mortality from various diseases around the world and dates of global interventions. We document that predicted mortality has a large and robust effect on changes in life expectancy starting in 1940, but no effect on changes in life expectancy before the interventions. The instrumented changes in life expectancy have a large effect on population; a 1% increase in life expectancy leads to an increase in population of about 1.5%. Life expectancy has a much smaller effect on total GDP both initially and over a 40-year horizon, however. Consequently, there is no evidence that the large exogenous increase in life expectancy led to a significant increase in per capita economic growth. These results confirm that global efforts to combat poor health conditions in less developed countries can be highly effective, but also shed doubt on claims that unfavorable health conditions are the root cause of the poverty of some nations.

Abstract:
Over the last 25 years, the US and the UK have experienced sharp increases in wage inequality and rapid deunionization. We argue that these two phenomena are related, and that skill-biased technical change has been an important factor in deunionization as well as in the rise in inequality. Skill-biased technical change causes deunionization because it increases the outside option of skilled workers, undermining the coalition among skilled and unskilled worker in support of unions. Our approach implies that although deunionization is not the underlying cause of the increase in inequality, it amplifies the direct effect of skill-biased technical change by removing the wage compression imposed by unions. We also show that deunionization may happen inefficiently.

Abstract:
We argue that the question of whether and when policy reform works should be investigated together with the political economy factors responsible for distortionary policies in the first place. These not only determine the initial distortions, but also often shape policy in the post-reform environment. Distortionary policies are more likely to be adopted when politicians are unconstrained and unaccountable to citizens. This reasoning implies that policy reform should have modest effects in societies where the political system already places constraints on politicians. It also implies, however, that in societies with weak political constraints, which are often those adopting the most distortionary policies, policy reforms may be ineffective because the underlying political economy problems are not typically altered by these reforms. Policy reform should therefore have its largest effect in societies with intermediate levels of constraints. In addition, when policy reform is (partly) effective, it may lead to a deterioration in other (unreformed) components of policy in order to satisfy the underlying demands on politicians - a phenomenon we call the seesaw effect. We provide reduced-form evidence consistent with these ideas by looking at the effect of central bank independence on inflation. The evidence is consistent with the notion that central bank reforms have reduced inflation in societies with intermediate constraints and have had no or little effects in countries with the high and low levels of constraints. We also present some evidence suggesting that, consistent with the seesaw effect, in countries where central bank reforms reduce inflation, government expenditure tends to increase.

Abstract:
This paper develops a simple model of economic and political institutions that lead to poor aggregate economic performance. In the model economy, groups with political power, the elite, choose policies to increase their income and to directly or indirectly transfer resources from the rest of society to themselves. The resulting equilibrium is generally inefficient because of three distinct mechanisms: (1) revenue extraction, (2) factor price manipulation and (3) political consolidation. In particular, the elite may pursue inefficient policies to extract revenue from other groups. They may do so to reduce the demand for factors coming from other groups in the economy, thus indirectly benefiting from changes in factor prices. Finally, they may try to impoverish other groups competing for political power. The elite's preferences over inefficient policies translate into inefficient economic institutions. The notable exception to this general picture emerges when long-term investments are important, thus creating a commitment (holdup) problem, whereby equilibrium taxes and regulations are worse than the elite would like them to be from an ex ante point of view. In this case, economic institutions that provide additional security of property rights to other groups can be useful.

Abstract:
While much research in political economy points out the benefits of "limited government", political scientists have long emphasized the problems created in many less developed nations by "weak states", which lack the power to tax and regulate the economy and to withstand the political and social challenges from non-state actors. I construct a model in which the state apparatus is controlled by a self-interested ruler, who tries to divert resources for his own consumption, but who can also invest in socially productive public goods. Both weak and strong states create distortions. When the state is excessively strong, the ruler imposes such high taxes that economic activity is stifled. When the state is excessively weak, the ruler anticipates that he will not be able to extract rents in the future and underinvests in public goods. I show that the same conclusion applies in the analysis of both the economic power of the state (i.e., its ability to raise taxes) and its political power (i.e., its ability to remain entrenched from the citizens). I also discuss how under certain circumstances, a different type of equilibrium, which I refer to as "consensually-strong state equilibrium", can emerge whereby the state is politically weak but is allowed to impose high taxes as long as a sufficient fraction of the proceeds are invested in public goods. The consensually-strong state might best correspond to the state in OECD countries where taxes are high despite significant control by the society over the government.

Abstract:
I review the two most popular explanations for the differential trends in wage inequality in US/UK and Europe: That relative supply of skills increased faster in Europe, and that European labour market institutions prevented inequality from increasing. Although these explanations go some way towards accounting for the differential cross-country inequality trends, it also appears that relative demand for skills increased differentially across countries. I develop a simple theory where labour market institutions creating wage compression in Europe also encourage more investment in technologies increasing the productivity of less-skilled workers, implying less skill-biased technical change in Europe than the US.

Abstract:
The paper provides a political economy theory of the Kuznets curve. When development leads to increasing inequality, this can induce political instability and force democratization on political elites. Democratization leads to institutional changes which encourage redistribution and reduce inequality. Nevertheless, development does not necessarily induce a Kuznets curve, and it is shown that development may be associated with two types of nondemocratic paths: An "autocratic disaster," with high inequality and low output, and an "East Asian Miracle," with low inequality and high output. These arise either because inequality does not increase with development, or because the degree of political mobilization is low.

Abstract:
Becker's theory of human capital predicts that minimum wages should reduce training investments for affected workers, because they prevent these workers from taking wage cuts necessary to finance training. We show that when the assumption of perfectly competitive labor markets underlying this theory is relaxed, minimum wages can increase training of affected workers, by inducing firms to train their unskilled employees. More generally, a minimum wage increases training for constrained workers, while reducing it for those taking wage cuts to finance their training. We provide new estimates on the impact of the state and federal increases in the minimum wage between 1987 and 1992 of the training of low wage workers. We find no evidence that minimum wages reduce training. These results are consistent with our model, but difficult to reconcile with the standard theory of human capital.

Abstract:
Most government expenditure is on goods that yield primarily private benefits, such as education, pensions, and healthcare. We argue that markets are most advantageous in areas where high-powered incentives are desirable, but in areas where high-powered incentives stimulate unproductive signalling effort, firms, or even government, may have a comparative advantage. Firms may be able to weaken incentives and improve efficiency by obscuring information about individual workers' contribution to output, and thus reducing their willingness to signal through a moral-hazard-in-teams reasoning. However, firms themselves may be unable to commit to not providing greater compensation to employees who distort their efforts to improve observed performance. Government organizations, on the other hand, often have to flatter wage schedules, thereby naturally weakening the power of incentives. We suggest that there are also endogenous reasons for why governments, even when they are run by self-interested politicians, may be able to commit to lower powered incentives than firms, because government operation makes yardstick comparisons, which increase the power of incentives, more difficult

Abstract:
For many problems in macroeconomics, development economics, labor economics, and international trade, whether technical change is biased towards particular factors is of central importance. This paper develops a simple framework to analyze the forces that shape these biases. There are two major forces affecting equilibrium bias: the price effect and the market size effect. While the former encourages innovations directed at scarce factors, the latter leads to technical change favoring abundant factors. The elasticity of substitution between different factors regulates how powerful these effects are, and this has implications about how technical change and factor prices respond to changes in relative supplies. If the elasticity of substitution is sufficiently large, the long-run relative demand for a factor can slope up. I apply this framework to discuss a range of issues including: Why technical change over the past 60 years was skill-biased, and why the skill bias may have accelerated over the past twenty-five years. Why new technologies introduced during the late eighteenth and early nineteenth centuries were unskill-biased. Why biased technical change may increase the income gap between rich and poor countries. Why international trade may induce skill-biased technical change. Why a large wage-push, as in continental Europe during the 1970s, may cause capital-biased technical change. Why technical change may be generally labor-augmenting rather than capital-augmenting.

Abstract:
This paper offers a model where firms decide what types of jobs to create and then search for suitable workers. When there are few skilled workers and the productivity gap between the skilled and the unskilled is small, firms create a single type of job and recruit all workers. An increase in the proportion of skilled workers or skill-biased technical change can create a qualitative change in the composition of jobs, increasing the demand for skills, wage inequality, and the unemployment rates for both groups. The paper provides some evidence that there has been a change in the composition of jobs in the U.S. during the past two decades.

Abstract:
We exploit the changes in the distribution of family income to estimate the effect of parental resources on college education. Our strategy exploits the fact that families at the bottom of the income distribution were much poorer in the 1990s than they were in the 1970s, while the opposite is true for families in the top quartile of the distribution. Our estimates suggest large effects of family income on enrollments. For example, we find that a 10 percent increase in family income is associated with a 1.4 percent increase in the probability of attending a four-year college.

Abstract:
Health expenditures as a share of GDP have more than tripled over the last half century. A common conjecture is that this is primarily a consequence of rising real per capita income, which more than doubled over the same period. We investigate this hypothesis empirically by instrumenting for local area income with time-series variation in global oil prices between 1970 and 1990 interacted with cross-sectional variation in the oil reserves across different areas of the Southern United States. This strategy enables us to capture both the partial equilibrium and the local general equilibrium effects of an increase in income on health expenditures. Our central estimate is an income elasticity of 0.7, with an elasticity of 1.1 as the upper end of the 95 percent confidence interval. Point estimates from alternative specifications fall on both sides of our central estimate, but are almost always less than 1. We also present evidence suggesting that there are unlikely to be substantial national or global general equilibrium effects of rising income on health spending, for example through induced innovation. Our overall reading of the evidence is that rising income is unlikely to be a major driver of the rising health share of GDP.

Abstract:
This paper offers and tests a theory of training whereby workers do not pay for general training they receive. The crucial ingredient in our model is that the current employer has superior information about the worker's ability relative to other firms. This informational advantage gives the employer an ex post monopsony power over the worker which encourages the firm to provide training. We show that the model can lead to multiple equilibria. In one equilibrium quits are endogenously high, and as a result employers have limited monopsony power and are willing to supply only little training, while in another equilibrium quits are low and training high. We also derive predictions from our model not shared by other explanations of firm sponsored training. Using microdata from Germany, we show that the predictions of the specific human capital model are rejected, while our model receives support from the data.

Abstract:
I analyze an economy in which profit-maximizing firms can undertake both labor- or capital-augmenting technological improvements. In the long run, the economy looks like the standard growth model with purely labor-augmenting technical change, and the share of labor in GDP is constant. Along the transition path, however, there is capital-augmenting technical change and factor shares change. A range of policies may have counterintuitive implications due to their effect on the direction of technical change. For example, taxes on capital income reduce the labor share in the short run, but increase it in the medium/long run.

Abstract:
The introduction of Medicare in 1965 was the single largest change in health insurance coverage in U.S. history. Many economists and commentators have conjectured that the introduction of Medicare may have also been an important impetus for the development of new drugs that are now commonly used by the elderly and have substantially extended their life expectancy. In this paper, we investigate whether Medicare induced pharmaceutical innovations directed towards the elderly. Medicare could have played such a role only if two conditions were met. First, Medicare would have to increase drug spending by the elderly. Second, the pharmaceutical companies would have to respond to the change in market size for drugs caused by Medicare by changing the direction of their research. Our empirical work finds no evidence of a "first-stage" effect of Medicare on prescription drug expenditure by the elderly. Correspondingly, we also find no evidence of a shift in pharmaceutical innovation towards therapeutic categories most used by the elderly. On the whole, therefore, our evidence does not provide support for the hypothesis that Medicare had a major effect on the direction of pharmaceutical innovation.

Abstract:
Many technologies used by the LDCs are developed in the OECD economies, and as such are designed to make optimal use of the skills of these richer countries' workforces. Due to differences in the supply of skills, some of the tasks performed by skilled workers in the OECD economies will be carried out by unskilled workers in the LDCs. Since the technologies in these tasks are designed to be used by skilled workers, productivity in the LDCs will be low. Even when all countries have equal access to new technologies, this mismatch between skills and technology can lead to sizable differences in total factor productivity and output per worker. Our theory also suggests that productivity differences should be highest in medium-tech sectors, and that the trade regime and the degree of intellectual property right enforcement in the LDCs have an important effect on the direction of technical change and on productivity differences.

Abstract:
In the standard model of human capital with perfect labor markets general training. When labor market frictions compress the structure of wages in the general skills of their employees. The reason is that the distortion in the wage structure" turn technologically' general skills into specific' skills. Labor market frictions and institutions such as minimum wages and union wage setting, are crucial in shaping the wage structure thus have an important impact on training. Our results suggest that the more frictional and" regulated labor markets in Europe and Japan may generate more firm-sponsored general training" than the U.S.
